Antiviral Cyanometabolites—A Review

Unfortunately, the number of effective and accessible medicines for the prevention and treatment of these infections is limited. Therefore, in recent years, efforts have been intensified to develop new antiviral medicines or vaccines. In this review article, the structure and activity of the most promising antiviral cyanobacterial products are presented. The antiviral cyanometabolites are mainly active against the human immunodeficiency virus (HIV) and other enveloped viruses such as herpes simplex virus (HSV), Ebola or the influenza viruses. The majority of the metabolites are classified as lectins, monomeric or dimeric proteins with unique amino acid sequences. They all show activity at the nanomolar range but differ in carbohydrate specificity and recognize a different epitope on high mannose oligosaccharides. The cyanobacterial lectins include cyanovirin-N (CV-N), scytovirin (SVN), microvirin (MVN), Microcystis viridis lectin (MVL), and Oscillatoria agardhii agglutinin (OAA). Cyanobacterial polysaccharides, peptides, and other metabolites also have potential to be used as antiviral drugs. -
DEVELOPMENT and EVALUATION of HIV Gp120 RESPONSIVE MICROBICIDE
DEVELOPMENT AND EVALUATION OF HIV gp120 RESPONSIVE MICROBICIDE FORMULATION FOR THE PREVENTION OF HIV SEXUAL TRANSMISSION A DISSERTATION IN Pharmaceutical Sciences and Chemistry Presented to the Faculty of the University Of Missouri-Kansas City in partial fulfillment of The requirements for the degree of DOCTOR OF PHILOSOPHY By Fohona S. Coulibaly B.S Chemical Engineering, INP-HB, Yamoussoukro, Ivory Coast, 2011 Kansas City, Missouri 2018 © 2018 FOHONA S. COULIBALY ALL RIGHTS RESERVED DEVELOPMENT AND EVALUATION OF HIV gp120 RESPONSIVE MICROBICIDE FORMULATION FOR THE PREVENTION OF HIV SEXUAL TRANSMISSION Fohona S. Coulibaly, Candidate for the Doctor of Philosophy Degree University of Missouri-Kansas City, 2018 ABSTRACT Sexual transmission of HIV remains the primary route (75 to 85%) of HIV infection among all new infection cases. Furthermore, women represent the most vulnerable population and are more susceptible to HIV infections than their male counterpart. Thus, there is an urgent need to develop topical (vaginal/rectal) microbicide formulations capable of preventing HIV sexual transmission. The objective of this dissertation is to develop a mannose specific, lectin-based topical microbicide formulation capable of targeting HIV gp120 for the prevention of HIV sexual transmission. In Chapters 1 and 2, the general hypothesis, aims and scope of this work are introduced. Chapter 3 covers the literature review of anti-HIV lectins and current delivery approaches. In Chapter 4, the binding interactions between the mannose specific lectin Concanavalin A (ConA) and glycogen from Oster, as well as mannan from Saccharomyces cerevisiae, were studied using a quartz crystal microbalance (QCM). The equilibrium dissociation constant describing the interaction between Con A and glycogen (KD = 0.25 μM) was 12 fold lower than the equilibrium dissociation constant describing the binding between Con A and mannan (KD = iii 2.89 μM). -
Novel Antiretroviral Structures from Marine Organisms
molecules Review Novel Antiretroviral Structures from Marine Organisms Karlo Wittine , Lara Safti´c,Željka Peršuri´c and Sandra Kraljevi´cPaveli´c* University of Rijeka, Department of Biotechnology, Centre for high-throughput technologies, Radmile Matejˇci´c2, 51000 Rijeka, Croatia * Correspondence: [email protected]; Tel.: +385-51-584-550 Academic Editor: Kyoko Nakagawa-Goto Received: 2 September 2019; Accepted: 19 September 2019; Published: 26 September 2019 Abstract: In spite of significant advancements and success in antiretroviral therapies directed against HIV infection, there is no cure for HIV, which scan persist in a human body in its latent form and become reactivated under favorable conditions. Therefore, novel antiretroviral drugs with different modes of actions are still a major focus for researchers. In particular, novel lead structures are being sought from natural sources. So far, a number of compounds from marine organisms have been identified as promising therapeutics for HIV infection. Therefore, in this paper, we provide an overview of marine natural products that were first identified in the period between 2013 and 2018 that could be potentially used, or further optimized, as novel antiretroviral agents. This pipeline includes the systematization of antiretroviral activities for several categories of marine structures including chitosan and its derivatives, sulfated polysaccharides, lectins, bromotyrosine derivatives, peptides, alkaloids, diterpenes, phlorotannins, and xanthones as well as adjuvants to the HAART therapy such as fish oil. We critically discuss the structures and activities of the most promising new marine anti-HIV compounds. Keywords: antiretroviral agents; anti-HIV; marine metabolites; natural products; drug development 1. Introduction Human immunodeficiency virus (HIV) infections pose a global challenge given that in 2017, according to the World Health Organization data, 36.9 million people were living with HIV and additional 1.8 million people were becoming newly infected globally (Table1) . -

Journal: Human Vaccines & Immunotherapeutics Pages: 1-3 Short Title: Are we ready for the new fatal Coronavirus: scenario of Pakistan? ISSN: 2164-5515 DOI: https://doi.org/10.1080/21645515.2020.1724000 Abstract: Scenario of Pakistan Pakistan, is the most affected countries, has experienced many diseases outbreaks and other disasters. Geographically and politically China and Pakistan are closely connected as shown in Figure 3. A large number of Chinese people are working in Pakistan on different developmental projects (China Pakistan Economic Corridor, Dams, Gawdar Port), and on the other hand many Pakistanis are residing in China carrying out their studies, business and jobs. The outbreak of coronavirus has appeared during the peak travel time when the Chinese from Pakistan and around the world are traveling to China, while the Pakistani community, especially students, are traveling back to Pakistan due to winter break. One of such case has been reported on 24 January 2020 after a person traveled from China to Pakistan on 21 January 2020 via Dubai and was diagnosed for 2019-nCoV on 24 January.3 However, the case was not notified officially by the government of Pakistan. In the depicted situation, the future is very alarming. After the ending of Chinese New Year celebrations, the Chinese will travel back to their jobs abroad, which may result in an outbreak of the fatal virus infection in Pakistan and other countries. -
